WEATHER-STRIP.

Specification of Letters Patent. pa'tnttgd Jun@ 2l Eiljlil.

Application lcd December 31, 1908. Serial No. 470,156.

granted to Charles C. Bowers on November.'

It has for its principal objects to exclude drafts :from the room, to exclude dust from the space between the window sash and the window frame, to conceal the weather strip, to facilitate the installation thereof, toacilitate the removing of the window sash, to

guard against the effects of the swelling and shrinking of the sash, to prevent the rattling of the sashes, and to provide for easy access to the sash weights without removing the weather strips.

The invention consists in the construct-ion and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part oi" thisspecitication, and wherein like symbols reier to like parts wherever they occur, Figure l is a vertical cross sectional view of a window embodying my invention, the intermediate portions thereof being broken away; Fig. 2 is a horizontal sectional view of a side olf a window embodying my invention with one of the sashes partly open; Fig. 3 is a similar view illustrating a modiied form of construction; and, Fig. 4 is a detail view of the eotiperating elements of the weather strip.

The window frame is of any ordinary construction. As illustrated in the accompanying drawing, it comprises jamhs l, the sill 2, a head 3, parting strips et, an inner stop 5, and an outer or blind stop (l. It also comprises an upper sash 7 tand a lower sash S. The jamhs are provided with vertical grooves for the parting strips, as usual.

Mounted on the inner face of the lower portion of each parting strip is; a strip f) of 'sheet metal which is substantially continuous with the lower sash in its lower or closed'position. On the marginal portion oi this stri) is formed a continuous head 10, prefer-ab y of the form illustrated in Fig. et.

In this form, the beadis a hollow or tubu-E lar rib which projects from the plane of the body of the strip and has its maximum width outside of said planef The tint portion ot this head strip is tacked or otherwise mounted tlatwise against the inneiiace of the portion of the parting strip that enters the groove in the jamh, so that the bead lies close to the inner face of the jamh. 'The outer portion of the inner facenti. the parting strip is slightly oti'set! or dressed oil;

andmounted onthe outer face of the lower" sash opposite this dressedv portion of the parting strip is a second metal strip ll Whose marginal portion l2 is curled or heut to form a laterally projecting groove which is the counterpart of the head of the metal head strip, that is, the mouth or gap of the groove is narrower than the portion of intermediate depth. rthe mouth or gap of the groove opens outwardly, that is, toward the parting strip or toward the tace of the sash. In order to accommodate the curled portion of the groove strip l1, the outer vertical edge oi the lower sash is rahheted or cut away to torni a groove 13. rllhe body portion of the metal groove strip Il is flat and it alone is tacked or fastened, leaving the groove portion free. The groove portion is sufficiently resilient to allow the head to he forced int; it. In this construction, the groove strip l1 is permanently fastened to the lower sash 8; so that in the mounting and dismounting of the lower sash, it, is merely necessary to remove the inner stop whereupon the niembers of the weather strip .may be sprung together or apart 'without dismounting` them.

TheA weather strip for the'upper sash is similar to that for the lower cash. In the construction illustrated in'Ifig. 0, the inner` vertical edge of the upper sash is rahheted or grooved; and in this rahhet or groove rests the curled marginal portion of the groove strip, the flat portion thereof being secured tlatwise against the outer tace of the groove in the jamb. In this construction, the head strip is mounted latwise against the inner face ot' the upper sash with its bead titting in the socket provided therefor in the groove strip.

In assembling the parts, the upper sash is positioned with respect to the outer or blind stop. Then the metalhad strips are .positioned to slide in the grooves of the metal groove strips; and while in this position, the

bead strips are tacked or otherwise mounted on the inner face of the upper sash; after which the parting strips are mounted in place.

In the construction illustrated in Fig. 3, the rabbets or grooves in the upper sash' are formed in the outer vertical edges thereof; and the metal groove strips are mounted on the outer face of the sash with their curled margins resting in said rabbets or grooves. In this construction, the bead strips are mounted on the outer or blind stops. By reason of the location of the weather guard in this construction, dust and dirt are excluded not only from the room but from the space between the sash and the jamb, and the upper sash may be removed without dismounting the weather strips. Forrthis purpose, the parting strips are firstremoved, the upper sash is let down to its lowermost position, in which positionall but the uppermost portions of the bead strips are disengaged from the groove strips, whereupon the sash is forced inwardly, permitting the easy disengagement of the.weather strips. Likewise to restore the outer sash to its place, this operation is simply reversed.

In the top of the window frame is a groove for' the parting bead 14, the inner side portion of this groove extending outwardly beyond the margin of the upper sash. The top of the upper sash is provided with a metal bead strip 15 whose bead fits in the marginal portion of the top groove. The bottom of the lower sash has a metal strip 16 fastened thereto which has a longitudinal groove mid- Way of its width, the grooved or curled portion lying in a groove provided therefor in the bottom of the sash. The sill 2 is provided with a bead strip 17 whose bead is positioned to coperate with said last mentioned metal groove strip 16. For this purpose, the opening of the groove strip is preferably wider than in the ease of the groove strips at the sides of the sashes, so as to make 1t easy to engage the bead therewith or disengage it therefrom. By this arrangement, the groove strip is better proportioned.

Mounted on the inner face of the meeting rail of the upper sash is a resilient plate whose-lower portion inclines away from said meeting 'rail and is provided with a flange that is rebent outwardly and has its marginal portion projecting part way into a horizontal groove provided therefor in said meeting rai rail of the lower sash is provided with a depression or ogee curve adapted to receive the projecting portion of said plate, said depression being rounded to accommodate said plate and to permit said plate to ride 'over the lower'portion of the meeting rail of the lower sash when the sashes. are moved up and down.

It is noted that the construction above de- The outer face of the meeting scribed has all the advantages incidental to the construction set forth in said Patent No. 805,115. Among the advantages peculiar to itself is the fact that the weather strips are protected from injury and cbncealed from view by the parting strips of the sashes, as well as those hereinbefore mentioned.

What l claim is:

1. A weather strip comprising a frame, a sash slidably mounted therein and having rabbets in its vertical edges, and counterpart metal bead and groove strips, said groove strips being mounted on the sash with their grooved portions in the rabbets and with the mouths of the grooves opening togvard the face of the sash.
